Shell has released a fresh plan to develop a major North Sea gas field which regulators initially rejected last year on environmental grounds.
The UK Government is expected to publish an energy transition strategy plan this week, which will put more focus on security of energy supply through domestic production.
Shell said in the new environmental development plan for Jackdaw that it aims to start production from the field, which will supply 6.5% of Britain's gas output, by Q3 or Q4 2025.
Following its release, the Jackdaw environmental plan will face a 30-day public consultation period after which the Offshore Petroleum Regulator for Environment and Decommissioning (OPRED) will review it.
A final decision on its development could be taken within 3 months if no new obstacles arise, according to Reuters.
The field has reserves of between 120 million and 250 million barrels of oil equivalent
The new plan changes the way Shell processes natural gas at the Shearwater hub.
Rather than removing all naturally-occuring CO2 from the gas offshore, some of it will be exported to the onshore St Fergus terminal where it will be further treated.
